I have had this system for about a year and a half and recently build a new system for someone and benchmarked it and decided to benchmark mine just for the sake of it and realized that my score seems to be fairly low.

Is there anything I could do, wrong bios settings perhaps? Because it looks like the i7 should perform a lot better than this according to different 3dmark benchmarks I saw. I know that the 4870 is not that good anymore, and I will upgrade when th 6xxxx comes out but other than upgrading my GPU, what's wrong with my system?
